I don't know about you, but when I've installed racing flywheels with as much mass removed from the periphery as possible to drop the MOI, acceleration/decceleration of the vehicle noticeably and measureably increases - and has nothing to do with a 'power increase'. If you want an assembly to spin up quicker you can either apply more power to it or you could reduce it's MOI - thereby reducing the effort/time needed to accelerate/deccelerate it. Wheel selection is the same way, select the wrong wheels with unneccesary mass concentrated at the periphery and you just slowed down your vehicles acceleration/decceleration. Select a same mass set of wheel with a maximized low MOI and you just increased the vehicles acceleration/decceleration. Same mass, different result - all depends on how its distributed.
Like I said in my initial post, don't really care about raising the power level as much as letting the engine do it's job easier and quicker through MOI reduction. The goal of a NA motor build to me is to increase responsiveness (the ability to accelerate/deccelerate the drivetrain quicker). Increasing power level doesn't necessarily give you a more responsive motor - it can, but it's not a given.

I WAS going to respond in my usual fashion.
However, since last night I have lost the will to live.....
Sure! Reduce weight of the engine & drivetrain rotating mass.
You will immediately feel a "HUUUUGE" increase in HP.
It will make this car great again.
